Thanks for this. This is something I have wondered about for a long time. It's not my intention to give people the evidence to do routine inductions on heavy women (which I am against) but trying to understand what's happening with my body. Honestly, I think much of my problem is an error in ultrasound dating. I just don't trust it. However, I did want to see if there was a correlation. Even though these studies do not approach the subject, perhaps routine induction is not the way to go. Maybe the babies of high BMI women are just not fully cooked - for one reason or another. Maybe that's why the body hangs on a bit longer. I don't know why that would be though.
When I was looking for a birth attendant this time around (my hb midwife was driven out of the biz) I checked some hospital midwife websites which said (in black and white) if you are this or this weight pre-pregnancy - that we will not be able to help you out. They are stigmatizing women without anything even happening. Most women start prenatals at what? 12 weeks? It's absurd. In the beginning, most women are healthy. Nobody is educated about how to eat in pregnancy - etc, etc, etc - so when they become 27-30 weeks - problems start. This is not a problem just with big women, but with everyone. My midwife says - and I tend to agree - that much of the sickness and pre-term births that women experience has to do with poor nutrition - rather than weight.
